Step 1

Pierce the potatoes with a fork. Wash and scrub 4 similar-sized sweet potatoes, then pierce each one all over with a fork.

Step 2

Prepare the steamer insert and add water. Set a heatproof trivet or steamer basket in an 6-quart Instant Pot or electric pressure cooker. Add 1 cup water and place the sweet potatoes on the trivet.

Step 3

Cook under high pressure for 12 to 25 minutes. Lock the lid on and check that the valve is set to seal. Set to cook for 12 minutes under HIGH pressure for small potatoes (6 to 8 ounces each), 18 minutes under HIGH pressure for medium potatoes (8 to 12 ounces each), and 25 minutes under HIGH pressure for large potatoes (12 to 16 ounces each). It will take 7 to 10 minutes to come up to pressure.

Step 4

Naturally release the pressure. When the cook time is up, let the pressure naturally release for 10 minutes. Quick release any remaining pressure. Open the pressure cooker and remove the sweet potatoes.
